 Seii's reign was relatively short, and defined by the interference and political abuses of his mother which led to an erosion of what little support the young king may have had from the territorial lords.It is important to note that the three "kingdoms" were little different from the loosely unified chiefdoms which came before, and the "kings" did not wield considerably greater power, nor were their administrations more organized or more politically stable than what came before.However, this became gradually less true over the generations; the king's power and organization advanced considerably by the time all three kingdoms were unified as the Kingdom of Ryukyu.
